The Wacker Neuson Fuel Tank Cap is a genuine OEM component designed for HDR 155 Direct Fired Radiant Heaters and HDR 45 direct fired radiant heaters. Sourced directly from Wacker Neuson, this cap carries the same part number and specification as the original, ensuring a correct, hassle-free installation every time. Whether you are servicing a fleet of HDR 155 units or a single HDR 45, the is the exact replacement your machine calls for.
Key Features
- OEM-Sealed Integrity — Manufactured to Wacker Neuson's exact venting and sealing specification, so the fuel tank maintains proper pressure balance during operation.
- Direct Drop-In Replacement — Matches the original tank neck thread pitch and cap diameter on HDR 155 and HDR 45 heaters for a straightforward swap with standard hand tools.
- Confirmed Fitment — Verified for the HDR 155 Direct Fired Radiant Heater and HDR 45 series; always cross-reference part number 5200011806 before ordering.
- Fuel Containment You Can Count On — A properly sealing tank cap prevents fuel vapors from escaping and keeps contaminants out of the tank, protecting downstream fuel system components.
- Fuel System Safety — A damaged or missing tank cap on a direct fired heater is a genuine fire hazard; replacing it promptly with the correct OEM cap keeps the machine operating within safe parameters.
The fuel tank cap seals the opening of the heater's fuel reservoir, keeping diesel securely contained while allowing the tank to breathe at the correct rate. A functioning cap prevents fuel spillage during transport and stops debris, moisture, and dust from entering the tank and fouling the fuel system. When a cap cracks, loses its seal, or goes missing entirely, the resulting fuel contamination or vapor escape can lead to hard-starting, erratic burner operation, and — on a direct fired heater — an elevated risk of ignition outside the combustion chamber.
